9 The Ethernet (802.3) MAC sub-layer standards govern the following data encapsulation function(s): Framing (frame boundary delimitation, frame synchronization) Addressing (handling of source and destination addresses) Error detection (detection of physical medium transmission errors) All of the above 10 Ethernet (and a few other layer 2 protocols) use MAC sub-layer addresses that are bits long. 16 bits 32 bits 48 bits 64 11 A device (i.e. by virtue of having a network interface) MUST have a UNIQUE MAC layer address within a LAN O True O False 12 AMAC sublayer address could be of the following type(s): Unicast Multicast Broadcast O All of the above 13 Which of the following is/are true about MAC layer broadcast address in Ethernet? (Select all that apply) The broadcast address is: FF-FF-FF-FF-FF-FF The broadcast address can appear in the Destination Address field in a Layer 2 frame The broadcast address can appear in the Source Address field in a Layer 2 frame The broadcast address is a predefined multicast address (i.e. a group address) that always denotes the set of all stations on a given LAN
